here is my RT_Siteconfig.pm and vbelow the lines from my httpd.conf 
which does the actual authentication

#RNING: NEVER EDIT RT_Config.pm. Instead, copy any sections you want to 
change to RT_SiteConfig.pm
# and edit them there.

# {{{ Base Configuration

# $rtname the string that RT will look for in mail messages to
# figure out what ticket a new piece of mail belongs to

# Your domain name is recommended, so as not to pollute the namespace.
# once you start using a given tag, you should probably never change it.
# (otherwise, mail for existing tickets won't get put in the right place

Set($rtname , "helpdesk......com");

# You should set this to your organization's DNS domain. For example,
# fsck.com or asylum.arkham.ma.us. It's used by the linking interface to
# guarantee that ticket URIs are unique and easy to construct.

# {{{ Incoming mail gateway configuration

# errors generated by the mail gateway to this address.  This address
# should _not_ be an address that's managed by your RT instance.

# If $ParseNewMessageForTicketCcs is true, RT will attempt to divine
# Ticket 'Cc' watchers from the To and Cc lines of incoming messages
# Be forewarned that if you have _any_ addresses which forward mail to

# "RTAddressRegexp" below, you will get yourself into a heap of trouble.

CC if

# incoming email addresses.  In its simplest form,

# create non-privileged accounts for unknown users if you are using
# the "LookupSenderInExternalDatabase" option.
# Instead, an error message will be mailed and RT will forward the
# message to $RTOwner.
# If you are not using $LookupSenderInExternalDatabase, this option
# has no effect.
# If you define an AutoRejectRequest template, RT will use this
# template for the rejection message.

# with it will get to the right place automatically.

# and comment mail tracked by RT, unless overridden by a queue-specific
# address.

#Sendmail Configuration

# $MailCommand defines which method RT will use to try to send mail
# We know that 'sendmailpipe' works fairly well.
# If 'sendmailpipe' doesn't work well for you, try 'sendmail'
# Note that you should remove the '-t' from $SendmailArguments
# if you use 'sendmail rather than 'sendmailpipe'
